📝 WalkthroughWalkthroughThe change adds 43-byte shielded addresses to DashPay profiles, introduces dedicated shielded tip accounts and recipient validation, and exposes the feature through Rust, Kotlin, Swift, JNI, persistence, migrations, protocol tests, and example applications.

`@packages/kotlin-sdk/KotlinExampleApp/app/src/main/java/org/dashfoundation/example/ui/dashpay/DashPayTabScreen.kt`:
- Line 328: Guard the shielded tip account lookup in DashPayTabScreen by
computing shieldedTipAccountIndex with remember(tipManager,
identity.identityIndex), wrapping the lookup in runCatching, and retaining only
a non-null result. Render ShieldedTipSheet only when that remembered result
exists, instead of invoking shieldedTipAccountIndex directly during composition.
In
`@packages/kotlin-sdk/KotlinExampleApp/app/src/main/java/org/dashfoundation/example/ui/dashpay/ShieldedTipSheet.kt`:
- Line 105: Update the ShieldedTipSheet send-error handling around submitted so
it resets submitted for every exception except
DashSdkError.PlatformWallet.ShieldedSpendUnconfirmed, preserving the locked
state only for that specific unconfirmed-spend error.
In `@packages/rs-platform-wallet/src/wallet/platform_wallet.rs`:
- Line 927: Update the account collection in the seedless rebind flow around
discovered_tip_accounts and bind_shielded_from_persisted so discovery-derived
accounts without persisted FVK rows in start.shielded.viewing_keys are skipped.
Preserve fallback behavior for explicitly required accounts and continue
rebinding accounts that have persisted rows.
In
`@packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Views/DashPay/DashPayProfileView.swift`:
- Line 24: Update the shieldedNotes `@Query` in DashPayProfileView to initialize
with PersistentShieldedNote.unspentPredicate(walletId:) using
identity.wallet?.walletId, so the query observes only this identity’s unspent
wallet notes; retain the existing accountIndex and isSpent filtering in
tipBalance.
In
`@packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Views/SearchWalletsForIdentitiesView.swift`:
- Line 366: Separate the throwing bindShielded call in discoverIdentities from
the discovery error handling so a binding failure does not discard the already
returned found result. Preserve found.count when reporting the failure, and
continue loading the preview for binding errors.

Issue being fixed or feature implemented
Let a DashPay user publish a reusable shielded tip address and receive payments by username. Wallet-generated addresses use a dedicated ZIP-32 account per identity, separating tip viewing keys from ordinary wallet activity. Users can also publish an externally generated Orchard address.
This follows the transparent profile-address work in #4380 and the 43-byte format in dashpay/dips#188. Contract, wallet, persistence, native bindings, and Swift/Kotlin example flows land together in this PR.
What was done?
profile.shieldedAddressto DashPay contract v2 at position 7: 43 raw bytes, including the full diversifier. Consensus enforces the byte length; clients validate Orchard decoding. Extend the protocol 13→14 migration/cache tests and update only the applicable fee/root fixtures.0x40000000 + index. Preparation verifies the seed, binds viewing keys, and flushes persistence before returning an address. Identity discovery reconstructs the account without relying on the current profile; retired tip accounts keep scanning. Ordinary balance/spending choices exclude tip accounts, with explicit access to tip funds.How Has This Been Tested?
Local macOS builds and targeted validation:
StateFlow.valuecomposition finding inSyncStatusScreen.kt:215.git diff --checkpasses. Storage explorer coverage passes for all 36 models, with a negative fixture verifying inherited-model omissions are detected.GitHub skips Rust and mobile runner jobs for this fork under the existing workflow trust policy; the results above are local validation.
Not exercised: a live funded network tip transaction, Android NDK/native
.sobuild, or Android device/instrumented execution. Full network end-to-end validation remains a release validation step.Breaking Changes
